Title:
METHOD FOR PRODUCING FLUORINE-CONTAINING OLEFIN
Document Type and Number:
WIPO Patent Application WO/2014/174918
Kind Code:
A1
Abstract:
The present invention provides a method for producing a fluorine-containing olefin by reacting a chlorine-containing compound represented by a specific general formula and anhydrous hydrogen fluoride in the presence of a fluorination catalyst containing chromium atoms, the method for producing a fluorine-containing olefin being characterized in that the reaction is carried out in a temperature range of 200-350°C in the presence of 0.0001-0.03 mol of molecular chlorine per mol of the chlorine-containing compound. The present invention makes it possible to maintain a good raw material conversion rate and good selectivity for the target compound while adequately exhibiting the effect of suppressing catalyst deterioration, and also to improve the harmful effects of using a large amount of non-condensable gas.
